An optical head compatible to IEC 62056-21 standard (available as an option) is

necessary to communicate with UGM G4 meter through the meter optical port.

The optical head is equipped with a magnetic hooking. To connect the optical

head to the meter, put the optical head in the appropriate circular groove on

the front of the meter with the cable facing down. The magnet and the circular

groove will hold the optical head in place.

UGM Communicator software developed by SmartMeterQ is available for

the communication with UGM G4 meter through the optical port. Contact

SmartMeterQ for more details.

5.2 Remote communication

UGM G4 meter is equipped with a GSM module dedicated to the remote

communication with the meter. Different models of GSM module are available

with different technologies (2G, 3G, NB-IoT, LTE Cat M1) and different

frequency bands (for different countries and areas of the world).

A SIM (Subscriber Identity Module) enabled for data transmission is necessary

to the GSM module to work.

For the SIM there are 3 possibilities:

a) micro SIM card (3FF size) (default)

b) eSIM (MFF2) (SIM inside an electronic component soldered on the electronic

board) (on request)

c) SIM integrated in the GSM module (on request) I

n case a) the customer can optionally provide to SmartMeterQ the micro SIM

cards that will be inserted in the UGM G4 meters in factory.

If the PIN (Personal Identication Number) request is enabled in the SIM, it

is necessary to congure in the meter the PIN (congurable, default: empty).

In the location of the meter installation there must be a GSM network coverage

of the GSM operator of the SIM compatible with the network technology and the

frequency bands of the GSM module inside the UGM G4 meter.

The GSM module is normally turned off by the meter in order to save the

Communication battery energy. The GSM module status (disabled or enabled)

is indicated in the meter display using the RF icon. When the GSM module is

turned on, the RF icon is displayed, otherwise the RF icon is not displayed.

The GSM module is turned on by the meter only when it is necessary to do a

data transmission and it is kept on only for the necessary time to do the data

transmission.

The meter periodically transmits the data to a remote Data Collection System

using the GSM module through a TCP or UDP socket. UDP socket is used

when TCP socket is not available (i.e. NB-IoT network). So it is necessary to

congure in the meter the APN parameters of the SIM (for the connection to

internet) and the IP address of the Data Collection System and the port number

used for the socket (for the data transmission).

It is possible to force an immediate data transmission using the meter User

Interface (meter display + buttons). See “User Interface” chapter for more

details.
